COLVIZEUND BLL BEARING.

.app'licationled January 26, 19521. Serial No. 439,96l.

To all whom izmay concer/nf y Be it known that I, GEORGE KENNEDY, a citizen ot the United States, residing at Gakdale, county of Stanislaus,State of (laliiorn-.ia, have invented certain new and useful improvements in Compound Ball Bearings; and l do declare thel following to be aY full, clear, and enact 4description of the same,.ref erence being had to the accompanying drawings, land to the characters or' reference marked thereon, which Yform a part of this application.

rl`his invention relates to improvements in ball bearings suchas are used extensively vin automobiles,` bicycles and motorcycles, and a j variety of other forms of machines and mechanisms. l

The principal object o1'LA my invention is to provide a compound bally bearing structure, which will be practically proof against :nontfunct-ioning due to the breakage ol any ball, as frequently and more or less inevitably occurs.k j l With the single ball races at present used,

the breakage ot one ball in `the race from anyV reason, soon causes the jamming of the shaft or the breakage oturther balls, resulting in the rapiddeterioration ot' the race andthe destroying of the easy running qualities which this torno of bearing is intended to give. j j Y By reason of my improved construction however, two concentrically alined sets of balls work together in unison, not only increasing the frictionless qualities of the bearing, but preventing any jamming from t'. ring place, since if one race should jam, the other takes up the load without detri nient to the jammed race or its contents.

fi. 'further object ot' the invention is to produce a simple and inexpensive device and yet one which will be exceedingly edective :tor the purposes which it is designed.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specilication and claims.

In the drawings similar' characters of reference indicate corresponding parts in the several views.

Fig. l is a sectional view of the front axle of an automobile, showing my improved bearingconstruction applied thereto as a tandem unit.

F ig. 2 is a similar view ot a single compound bearing unit, suitable for rear axle use, or for vgeneral shatting purposes.

Referring now more particularly to the characters et reference on the drawings, and especially at present to F ig. l, the numeral l denotes the hub ot the wheel, inthe bore 2 ot which are lined oppositely disposed races 3 and el, situated adjacent the inner and outer ends ot the hub respectively.

Balls 5 are seated in the inner race 3 and are engaged by a race-cone 6 formed at'one end or" a tubular sleeve 7, on the other and outer end oi which is screwed another cone 3 engaging the balls 9 in the race 4. This cone mayk be adjusted on the sleeve and held at any desired point of setting by means of a set screw l() seated haii1 in the sleeve and halt in the cone, the latter having a plurality ot semicircular and tapped orifices or recesses as at ll around its inner periphery, while the sleeve is only provided with a single .complementary recess. "ln this nianner the cone may be advanced or retracted on the sleeve to take up any lost motion in the inner and outer bearing members, and the cone n iaythen be held at any point where one ot the cone recesses registers with the sleeve recess to i'orm the set screw hole.

Formed on the inside ot the inner cone (l is anotherl race 19 'carrying balls 13 engaged by a cone lay-formed at that end ot the axle or spindle l5, the outer end of which is threaded to receive a tapped cone 16 engaging balls l? seated in a race 18 formed on the inside ol" the cone 8 and in opposed relation to the race l2. Adjust ment of the cone 16 and locking thereof is effected by means or a locknut 19 ot any' suitable form. it being noted that the adjustment ot' the first named or out-er bearings is separate 'lroni that 'for the other bearings, all ot' which are ot course concentric with the aXle l5.

The bearings at the inner end oi the spindle are protected from dirt and dust b v means of any suitable Afelt packing or washer as at 2O while the outer end bearings are enclosed in a removable cap 2l oi any desired form, secured to the hub l.

The type oi'f bearing illustrated in Fig. is built on the same principle as the structure just described, but forms a single compound unit of itself, of the annular type.

This structure comprises an outer ring 22. adapted to be fitted into a bearing box, and

which is ani interniil andeentrally disposed i'eo`es`s`23 forniihg' zt race for' balls 24, which also beer against similariy lbut oppositely disposedcones 25, formed half on each of male :ind female rings 26 and 27 respectively.

These rings are joined together and adj usted in the following manner The member 26 has si threaded flange" 28 :idziptedto sorexvinto ziA tapped groove or reo 291` in the".feihaile" nienibeli 27. l
